Myproblem is with Pro tools 12. In normal mode I am not showing wave forms during recording. They are there after recording and playback. Waveforms is set, not block or something else. I know with some of the other options,like Quick Punch, the wave forms do not show while recording.

I have the same problem of the waveform not showing up in 11. When I open the session in 10 it draws the waveforms just fine, then I re-open in 11 and they are there. Quite a workaround and waste of time, but the only way I can get it to work.

I have this problem occasionally and found a workaround. Select the region(s) in question... then look under VIEW> WAVEFORMS> and toggle between "Peak" and "Power" a couple of times. Usually works for me. You may have to increase the size of the waveforms, too.
